Designed specifically for the ArmaLite® AR-50™ rifle, these heavy-duty rests provide a stable platform for accurate shooting with this big .50 BMG boomer. The solid-steel Bipod attaches to the AR-50 forearm, and features lockable cant adjustments and positive screw-lock legs with ski feet. The bipod’s wide, 17" stance offers stability, and it can even be used to hold the rifle’s muzzle down for cleaning the bore.
